HYDROCARBON BURNER Filed Nov. 17, 1927 2 Sheets-Sheet @www Patented Dec.3l, 1929 imitan STATES PATENT loI-rica JAMES L. BREESE, JB., OF CHICAGO,ILLINOIS, ASSIGNOR TO OIL DEVICES COBIOMTION, OF CHICAGO, ILLINOIS, ACORPORATION OF ILLINOIS HYDnooARBoN BURNER My invention relates toadevice for burning hydrocarbons, which is particularly 4adapted for theburning, in heating plants,

A of a liquid hydrocarbon. One object of my 5 invention is to provide asimple and easily manufactured complete fuel supply and heating unitadapted for installation in any suitable heater. Another object is theprovlslon of clamping means for sealing oil' the air in the ash pitdoor. Other objects will appear from time to time in the course of thespeclcationand claims.

I illustrate my invention more or less diagrammatically 1n the'accompanying drawi ings, wherein- Figure' 1 is a perspective view of mydevice, showing the heating unit withdrawn from lthe heater or stove; Y

Figure'2 is a vertical section ofthe heating` unit positioned within theheater;

igure 3, is a section along the line 3-3 of Figure 2;

-Figure 4 is an enlarged top plan view of the combination oil and gasinlet;

Figure 5 is a section along the line 5-5 of Figure 4; and

Figure 6 is a vertical section along the line 6-6`of Figure 5.

Like parts are indicated by like symbols throughout the speciiicationand drawlngs.

It will be realized that I describe and illustrate a complete fuelvsupply and burner unit which is adapted to be used with any suitableheater, the combustion member of the burner being for example placedwithin the ash pit of a coal burning heater.

A generally indicates a heater of a well known type having the usualsupporting legs A1, a flue escape pipe A2 and a fire dox door A3.

B indicates a fuel suppl and heater unit having a combustion mem er B1.The latter includes a bottom ortion B2 resting upon the bottom of the aspit A4 of the heater A, and provided with the upwardly projectinggenerally cylindrical wall B3 in communication with which is thelongitudinal airl inlet passage B", which is braced by the member B5 tothe wall B3. Said wall may be provided with indentations Bv for clearingthe lugs A*s or other projections inside the ash pit opening;

Seated upon the upper edge of said wall is a mixing chamber having thebottom portion C which may be concavev as'shown and the upwardlyprojecting cylindrical side wall C1, which may be made of two parts C2 Csecured together by the crimp C4. Cs are a plurality of large and smallapertures penetrating the upper part C3 of the wall, ermitting air toenter the mixing cham er. Exteriorly projecting from the wall C1 is acircular flange C with a downwardly projecting ring C1 adapted to beseated upon the upper edge of the drum B3. C8 is a conic shaped splitring positioned inl the circular depression or groove C9 in the wall C1.l

D generally indicatesa gas and fuel inlet having a top portion D1 whichmay be hexagonalin shape, and has an annular channel D2 in its lowerside. Projecting downwardly from the portion D1 and centrally locatedwithin said channel D2 is the conical ortion D8 associated with adownwardly ex nding stem D4 having an outwardly projecting flange D5with a conical-shaped end portion D". As best illustrated in Figures 5and 6 ,the flange Dl5 and conical end portion D1 seat in acorrespondingly shaped depressed portion C10 centrally located andintegral with the concave bottom C of the mixing chamber. D7 are aplurality of passages in the stem Df, extending from the fuel passageD8. D9 are a plurality of downwardly inclined gas outlet passagesextending from the chamber D10 above the tube or pipe D11 screwthreadedinto the member D as at D12. The other end of said stub pipe is threadedinto the member E as at E1. The member E is an elbow with a sidefoutlet.It is provided with a seat E2 adapted to receive the correspondinglyshaped depressed portion C10. The member from the fuel passage E4 bymeans of a wall E2. E7 is a gas supply line communicating with thepassage E5. As best vshown in Figures 4, and 6, gas for the ,necessarypilot 5 lights for igniting of the liquid hydrocarbon fuel has freeaccess to the mixing chamber by means of thepassageE, tube D11 andassage D1o communicating with the gas outets D". The downwardly inclinedflames of m the pilot lights will be in the direct path of the liquidfuel flowing through the apertures D7. Integral with the member E is aboss E downwardly projecting through the hole B7 located in the upwardlydepressed 15 portion B2 of the bottom B2. E12 is an aperture in the bossE1o adapted to receive the locking pin E13, thus securing the mixingchamber to the air drum B3.

F indicates a fuel tank having a conical bottom plate F1. F2 is a fuelcontrol valve v#responding to the action of the float F3 in theiioatchamber F4. Upwardly extending above the r'upper edge of the fuel tank Fis the rotary stem F5 for controlling the flow '25 of liquid fuelthrough the valve F2. F6 is a cover. The float chambery F4 is providedwith an outwardly projecting circular flange .F7 upon which is seatedthe fuel tank F, centered by means of the upwardly extending o flan .eF8 and held in place by the split locking ban F. Mounted in the fiangeF7 at'either side of the float chamber are the supporting rods lF1o F10,having the adjustable base members F11' with locking screws F12.

Communicating with the float chamber F4 is the upwarly extending pipe Gassociated with the fuel line E2. As illustrated in Figures 2 and 3,vthe fuel line E3 and gas supply pipe E7 are positioned within the air.inlet assage B2 which may be supported by braces him or other suitablemeans. The fuel line E3 is provided with a control valve G1 havingr theupwardly protruding handle G2.

Figures 2 and 3 illustrate the heating unit j with the combustion memberpositioned withl in the ash pit A4. The usual ash pit door of the heaterA has been removed and been replaced by the closure plate H cut away asat H1 to conform to the shape of the laterally projecting air passageB". H2 is a locking member, hinged as at H3 to the usual pin H4 providedfor'the ash pit door. H5 H5 are spring members mounted on the member H2adapted for frictional engagement with the plate H, pressure beingapplied by means of the screwthreaded stud H6 mounted in the heater Aand penetrating the locking member H2 and the wing nut H7.

It is understood that the usual grating associated with the heater` Amay preferably'be removed as shown, leaving free access to thecombustion chamber A7.

It will be realized that whereas I have shown a practical and operativedevice, nevertheless many changes might be made in size, shape, numberand distribution of parts vplant is of greatimportance.

Referring to the unit itself oil flows from the float chamber F4 alongthe line E3 to the elbow member shown in detail in Figures 4, 5 and 6.The elbow member also receives gas through the line E7.' Itv will benoted that the gas and oil ilow upwardly through the same member,although being supplied of course through different ducts to the bottomof the mixing chamber. The gas jets which pass `through apertures Dincline downwardly into the path of delivery of the oil through thepassages D7, the gas jets being vertically aligned with the oil ducts.

In order to prevent the inow of air through the grate door, the gratedoor being removed, I provide the structure shown in detail in Figures 2and 3 which includes the plate H, cut away as at H1 to conform to theair' passage'E, upon' which it may rest. In order to hold it against theedges of the grate door I provide vertical spring arms' H5 which aresecured to the transverse strip H2, one end of which is hinged to the`normal pivot pin H2 of the ash pit door, whereas the other is securedat the opposite side of the door, fory example bythe screwthreaded studHe and the' ring nut H7. yielding pressure against the closure member H,which keeps it tightly sealed in place the pressure being appliedparticularly to the four corners of the plate.
